Squamous cell carcinoma (SCC) is an uncontrolled growth of abnormal cells arising in the squamous cells, which compose most of the skin’s upper layers (the epidermis). SCCs often look like scaly red patches, open sores, elevated growths with a central depression, or warts; they may crust or bleed. They can become disfiguring and sometimes deadly if allowed to grow. An estimated 700,000 cases of SCC are diagnosed each year in the US, and between 3,900 and 8,800 people died from the disease in the US in 2012.

Basal Cell Carcinoma (BCCs) are abnormal, uncontrolled growths or lesions that arise in the skin’s basal cells, which line the deepest layer of the epidermis (the outermost layer of the skin). BCCs often look like open sores, red patches, pink growths, shiny bumps, or scars and are usually caused by a combination of cumulative and intense, occasional sun exposure.

The American Academy of Dermatology recommends wearing an SPF of 15 or higher for maximum protection. Look for a product that states, “UVA/UVB,” protection or has “broad spectrum” on the label as it is important to protect against both spectrums.If looking for a sunscreen to use in the water, look for one that says “waterproof” or “water resistant.” Waterproof should provide 80 minutes of protection and water resistant should provide 40 minutes of protection.

SPF stands for sun protection factor. It is a measure of ultraviolet B protection. It is the amount of light that induces redness in sunscreen-protected skin, divided by the amount of light that induces redness in non sunscreen-protected skin.

For example, a sunscreen with an SPF of 15 will delay the onset of a sunburn in a person who would otherwise burn in 10 minutes to burn in 150 minutes. So SPF 15 sunscreen allows a person to stay out in the sun 15 times longer. It is important to remember that SPF does not predict ultraviolet A protection.

Mohs surgery has come to be accepted as the single most effective technique for removing Basal Cell Carcinomas and Squamous Cell Carcinomas (BCCs and SCCs), the two most common skin cancers. It accomplishes the nifty trick of sparing the greatest amount of healthy tissue while also most completely expunging cancer cells; cure rates for BCC and SCC are an unparalleled 98 percent or higher with Mohs, significantly better than the rates for standard excision or any other accepted method.
